Hi all people,
I am a newbei to this posting. Should I select a wrong subject posting following message kind accept my apology and advise me the appropriate subject making this posting
I am venturing to make a VoIP phone. Could I use only AT89C52 (8052), a single chip, to do following function.
2) TCP/IP connection via broadband
3) ADC and DAC (analog to digital and digital to analog)
4) Modem connection via PSTN
If possible kindly advise where could I find relevant information, both schematics and programming sample.
